The scope of ge- netic engineering
Genetic engineering is the area of biotechnol- ogy concerned with the directed alteration of genetic material.
Biotechnology has already had countless appli- cations in industry, agriculture, and medicine. It is a hotbed* of research. The finishing of the human ge- nome project – a “rough draft” of the entire human genome was published in the year 2000 – was a sci- entific milestone** by anyone’s standards. Research is now shifting to decoding the functions and inter-
actions of all these different genes and to developing applications based on this information. The potential medical benefits are too many to list; researchers are working on every common disease, with varying de- grees of success. Progress takes place not only in the development of drugs and diagnostics but also in the creation of better tools and research methodologies, which in turn accelerates progress.
When considering what developments are likely over the long term, such improvements in the research process itself must be factored in***. The human ge- nome project was completed ahead of schedule (it usually takes ten years to get from proof-of-concept to successful commercialization).
Genetic therapies are of two sorts: somatic and germ-line. In somatic gene therapy, a virus is typically used as a vector to insert genetic material into the cells of the recipient's body. The effects of such inter- ventions do not carry over into the next generation. Germ-line genetic therapy is performed on sperm or egg cells, or on the early zygote, and can be inherit- able. Embryo screening, in which embryos are tested
extroversion, conscientiousness, physical appearance, etc. – involve genetic predispositions. Single-gene disorders, such as cystic fibrosis, sickle cell anemia, and Huntington's disease are likely to be among the first targets for genetic intervention. Polygenic traits and disorders, in which more than one gene is impli- cated, may follow later, although even polygenic con- ditions can sometimes be influenced in a beneficial direction by targeting a single gene.
Notes
*hotbed – a place where a lot of particular kind of activity happens.
**milestone – a very important event in the de- velopment of smth.
***to factor in – to include a particular thing in your calculations about how long something will take, how much it will cost etc.

for genetic defects or other traits and then selectively implanted, can also count as a kind of germ-line inter- vention. Human gene therapy, except for some forms of embryo screening, is still experimental. Nonethe- less, it holds promise for the prevention and treatment of many diseases, as well as for uses in enhancement medicine.

It’s in our genes. Heredity. Our mothers and fa- thers passed on all our traits when we were born. There are also many things in our genes that we would rather avoid, such as heart disease, diabetes, cancer, arthritis, muscular dystrophy, and other ill- nesses.
Many diseases come from alterations in our genes. To decipher our genetic code, a scientific journey has begun called The Human Genome Pro- ject. The genetic code is the complete instructions of all the genes that tell our body how to develop.
Over the years, some genes have been discovered for certain diseases. People who have a family his- tory of these diseases can be tested for the specific
gene. They will then know if they
have this disease, even if no symptoms are pre-
sent. But there are many more diseases with genetic compo- nents that have not yet been uncovered. Scientists are still unclear what or which genes affect those diseases. Francis Collins MD, PHD, is the Project Director at the National Center for Human Genome Research. He said that “by uncovering all 30,000 to 40,000 genes in the human genome, we should at the same time uncover the heredity basis of most dis- eases and that would put us in a position to diagnose them better, treat them better and practice better pre- ventative medicine.”
What are Genes? They are found in the part of the cell called the nucleus. Human cells contain 23 pairs of chromosomes, 46 in all. One member of each pair comes from the mother and one from the father. Genes occur in pairs, like the chromosomes. A chromosome is a very long chemical molecule called DNA. Genes are segments of DNA mole- cules. DNA is shaped like a twisted ladder. Rungs of the ladder are chemicals called “base pairs”. Chemical “A” is always paired up with “T” and “G”
is always with “C”. The complete human genome (all our DNA) contains three billion “base pairs”. The Human Genome Project will find the sequence of all of them. This knowledge will revolutionize our understanding of the way genes influence disease, because the genes’ “base pair” sequence is the code that determines what it does.
What do genes do? They give cells the instruc- tions they need to make complex molecules called proteins. Each gene code is for a different protein. A cell first converts DNA to a similar molecule called RNA. RNA carries the gene’s instructions to another part of the cell that acts like a protein fac- tory. Most proteins that come out of the factory are enzymes. Other proteins form cell structures.
Occasionally, the gene that codes for a protein has an error in its based pair sequence. The cell then makes a protein that is not able to do what it should. This is called a mutated gene. Mutated genes play a major role in human diseases. Since genes are in- credibly small, it is difficult for scientists to isolate them. Making it easier for scientists to find disease- causing genes is the main goal of the Human Ge- nome Project.

One of the best-known and controversial appli- cations of genetic engineering is the creation of genetically modified food. There are three generations of genetically modified crops. First generation crops have been commercialized and most provide protec- tion from insects and/or resistance to herbicides. There are also fungal and virus resistant crops devel- oped or in development. They have been developed to make the insect and weed management of crops easier and can indirectly increase crop yield.
The second generation of genetically modified crops being developed aim to directly improve yield by improving salt, cold or drought tolerance and to increase the nutritional value of the crops. The third generation consists of pharmaceutical crops, crops that contain edible vaccines and other drugs. Some agriculturally important animals have been geneti- cally modified with growth hormones to increase their size while others have been engineered to express
drugs and other proteins in their milk.
The genetic engineering of agricultural crops can increase the growth rates and resistance to different diseases caused by pathogens and parasites. These modified crops would also reduce the usage of chemi- cals, such as fertilizers and pesticides, and therefore decrease the frequency of the damages produced by these chemical pollution.
Ethical and safety concerns have been raised around the use of genetically modified food. A major safety concern relates to the human health implica- tions of eating genetically modified food, in particular whether toxic or allergic reactions could occur. Gene flow into related non-transgenic crops, off target ef- fects on beneficial organisms and the impact on biodiversity are important environmental issues. Ethi- cal concerns involve religious issues, corporate con- trol of the food supply, intellectual property rights and the level of labeling needed on genetically modified products.

Генетически модифицированные организмы создаются методами генной инженерии - науки, которая позволяет вводить в геном растения, жи- вотного или микроорганизма фрагмент ДНК из любого другого организма с целью придания ему определенных свойств. Например, томаты полу- чили ген морозоустойчивости от арктической камбалы, картофель получил ген бактерии, чей яд смертелен для колорадского жука, рис получил ген человека, отвечающий за состав женского мо- лока, который делает злак более питательным.
Экспериментальное создание генетически модифицированных организмов началось еще в 70-е годы XX века. С этого времени производство ГМП набирало обороты и сейчас мы можем встретить ГМ сою, кукурузу, рис, картофель, по- мидоры, рапс, сахарную свеклу, пшеницу, горох, подсолнечник, папайю, хлопок, табак, коров с по- вышенной жирностью молока, лосося, который может жить как в соленой, так и в пресной воде и многих других организмов.
Неконтролируемое потребление генетически модифицированных продуктов может иметь не- предсказуемые последствия в будущем. Чтобы полностью понять все риски употребления в пищу трансгенных продуктов, должно пройти несколько десятков лет и смениться несколько поколений, питавшихся ГМП.
Но нельзя говорить со стопроцентной уве- ренностью о вреде всех трансгенных продуктов. И в природе существуют организмы, непригодные в пищу для человека (ядовитые и мутагенные). Че- ловек сам вправе выбирать, как жить и чем пи- таться. Главное, чтобы этот выбор был осознан- ным и основывался на научно доказанных фактах, а не на слухах.

Do you know how stem cell is used in treatment of different diseases?
Are stem cells used nowadays? How?
1. Read this text and compare your idea of stem cells and the one given below.
Our future hope?
Stem cells are cells found in most, if not all, multi- cellular organisms. They are characterized by the abil- ity to renew themselves through mitotic cell division and differentiating into a range of specialized cell types. Research in the stem cell field grew out of find- ings by Canadian scientists Ernest McCulloch and James Till in the 1960s.
The two types of mammalian stem cells are: em- bryonic stem cells that are found in blastocysts, and adult stem cells that are found in adult tissues. In a de- veloping embryo, stem cells can differentiate into all of the specialized embryonic tissues. In adult organ- isms, stem cells and progenitor cells act as a repair system for the body, replenishing specialized cells, but also maintain the normal turnover of regenerative or- gans, such as blood, skin or intestinal tissues.
To ensure self-renewal, stem cells undergo two types of cell division. Symmetric division gives rise to two identical daughter cells both endowed with stem cell properties. Asymmetric division, on the other hand, produces only one stem cell and a progenitor cell with limited self-renewal potential. Progenitors can go through several rounds of cell division before terminally differentiating into a mature cell. It is pos- sible that the molecular distinction between symmetric and asymmetric divisions lies in differential segrega- tion of cell membrane proteins (such as receptors) be- tween the daughter cells.
Stem cells can now be grown and transformed into specialized cells with characteristics consistent with cells of various tissues such as muscles or nerves through cell culture. However, their use in medical therapies has been proposed.
The classical definition of a stem cell requires that it possess two properties:
Self-renewal - the ability to go through numerous cycles of cell division while maintaining the undiffer- entiated state.
Potency - the capacity to differentiate into special- ized cell types.
Properties of stem cells can be illustrated in vitro, using methods such as clonogenic assays, where sin- gle cells are characterized by their ability to differenti- ate and self-renew. As well, stem cells can be isolated based on a distinctive set of cell surface markers. However, in vitro culture conditions can alter the be- havior of cells, making it unclear whether the cells
will behave in a similar manner in vivo. Considerable debate exists whether some proposed adult cell popu- lations are truly stem cells.
Medical researchers believe that stem cell therapy has the potential to dramatically change the treatment of human disease. A number of adult stem cell thera- pies already exist, particularly bone marrow trans- plants that are used to treat leukemia. In the future, medical researchers anticipate being able to use tech-
 |
nologies derived from stem cell research to treat a wider variety of diseases including cancer, Parkinson's disease, Alzheimer’s disease, spinal cord injuries, Amyotrophic lateral sclerosis and muscle damage, amongst a number of other impairments and condi- tions. However, there still exists a great deal of social and scientific uncertainty surrounding stem cell re- search, which could possibly be overcome through public debate and future research, and further educa-
tion of the public.
